Predictive dormancy occurs when an organism enters a dormant phase before the onset of adverse conditions. For example, photoperiod and decreasing temperature are used by many plants to predict the onset of winter. Consequential dormancy occurs when organisms enter a dormant phase after adverse conditions have arisen. This is commonly found in ...
Latent buds – axillary buds whose development is inhibited, sometimes for many years, due to the influence of apical and other buds. Also known as dormant buds. Lateral buds – a bud located on the side of the stem, usually in a leaf axil. Late wood – the portion of the annual ring that is formed after the formation of earlywood has ceased.
Drunken trees, tilted trees, or a drunken forest, is a stand of trees rotated from their normal vertical alignment. [ 1 ] [ 2 ] This commonly occurs in northern subarctic taiga forests of black spruce ( Picea mariana ) under which discontinuous permafrost or ice wedges have melted, [ 3 ] [ 4 ] causing trees to tilt at various angles.
Epicormic buds lie dormant beneath the bark, their growth suppressed by hormones from active shoots higher up the plant. Under certain conditions, they grow into active shoots, such as when damage occurs to higher parts of the plant, [ 1 ] or light levels are increased following removal of nearby plants. [ 2 ]
Compared to modern trees, the stems and branches of the lycopsids contained little wood with the majority of mature stems consisting of a massive cortical meristem. The nearly-uniform growth of this cortical tissue indicates no difference in growth during changing seasons, and the absence of dormant buds further indicates the lack of ...
Dendrology (Ancient Greek: δένδρον, dendron, "tree"; and Ancient Greek: -λογία, -logia, science of or study of) or xylology (Ancient Greek: ξύλον, ksulon, "wood") is the science and study of woody plants (trees, shrubs, and lianas), specifically, their taxonomic classifications. [1]
The trees favour good, loamy sites, but can also be found on sandy, infertile soils, and are not thought to be drought resistant. Dormant shoots of Tilia cordata can resist winter frost temperatures as low as −34 °C (−29 °F). [8] Processed, dyed small-leaved lime (Tilia cordata) pollen.
European beech (Fagus sylvatica) bud. In botany, a bud is an undeveloped or embryonic shoot and normally occurs in the axil of a leaf or at the tip of a stem.Once formed, a bud may remain for some time in a dormant condition, or it may form a shoot immediately.
